Demi Lovato “Stone Cold” (NEW VIDEO)

The emotional four-minute visual features Demi trekking across Utah’s snowy mountainous landscape. In an interview with ET, the 23-year-old said this video was the “hardest” she’s ever shot:

“One, because emotionally it’s difficult, but two, at one point, I’m in the snow and it’s up to my waist—that’s literally how deep the snow was—so when you have like three pairs of leggings and you’re in the snow, and it’s not snow pants, I wrung my pants afterwards. It was just soaking wet because I had been in the snow for so long.”
